Close Board on Upgrade

Automatically closes the board when a MyBB forum or plugin upgrade becomes available.

Automatically closes the board when a MyBB forum upgrade or an upgrade to
an active plugin becomes available. There are three components to this
plugin (each component is optional):

- A plugin that works with the built-in "Check For Updates" features.

- A task that is set to periodically run to check for upgrades to the main
forum package.

- A task that is set to periodically run to check for upgrades to installed
and activated plugins.

This package also works with my 'Open/Close Board Send E-mail' plugin so
you can get an e-mail notification when the board closes due to upgrade
availability.

And, of course, full multilingual support.

NOTE: Installation is a bit more involved compared to most plugins. The
screenshot doesn't really do this package justice - the closed board text
can be configured to say whatever you want to your users.
